SPECIFICATION forming part of Letters Patent No. 492,144, dated February21, 1893.

Application filed May 2l, l890. Serial No. 352,636. (No model.)

To all whom t may concern:

Be it known that I, GEORGE S. COX, a citi-- zen of the United States,residing at Philadelphia, county of Philadelphia, and State ofPennsylvania, have invented a new and useful Improvement in Looms, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, which form a part of thisspecification.

The object of my improvement is to enable the rapid and ready productionof blind passes or the formation ot' warp without filling, so that atIthe ends of the fabric, such as towels, I can obtain a sufficientextent of warp to produce fringe.

My improvement consists in certain attachments 'to looms whereby thetension on the warp is released, and, at the same time, the sand rolleris caused to move rapidly so as to carry forward a sufficient extent ofWarp to form the fringe of any desired length.

In the drawings:-Figure 1 is a side elevation of a portion of a loomembodying myinvention. Fig. 2 is a front elevation of portion of loom.Fig. 3 is a side elevation of portion of loom,-the side opposite to thatof Fig. l. Fig. 4 is a perspective View of detached parts. v

Similar letters denote similar parts.

A is the ordinary shuttle box lever which is connected to the liftingrod aso as to bring the desired shuttle into position to be operated bythe picker staff. This lever is operated under the control of, thepattern chain B, which has projections or lugs of differentl heights andsaid pattern chain generally moving one sprocket for every two picks.Said projections act on the weighted feeler lever b which is connectedto the rod b', which in turn is connected to the ordinary anchor b2,which anchor is given a vertical reciprocatory motion in the ordinarymanner.

On the box lever A are a series of steps a', a2, duc. and the weightedfeeler lever b brings the anchor into such position that it strikesdifferent steps depending upon the extent of projection upon the patternchain, and by this means the desired box is brought into position to beacted upon by the picker staff as in an ordinary loom.

C is the sand roller which moves the cloth forward as it is made.

d is the shoe attached to the lifting rod a, upon which the shuttle boxlever acts to lift the shuttle box.

dis a ring loosely surrounding the lifting rod and resting upon thisshoe. To this ring is attached a spring d2, and a string or chain d3also is attached to this ring d', which string or chain passes over apulley d4 on the front of the loom on the back of the breast beam d5 andpasses along thevback of this breast beam to the opposite side of themachine to pulley d6 and passes around a roller c2@ on the shaft e andover pulley dl attached to the lever E, on the gear shaft e. Connectedto this lever are the pawls e', e2, one on each side (see Fig. 4). Thestring or chain passes from the pulley d6 around the shaft e and overpul l ley d", on the lever E and is connected to the pawls e', e2, itdividing out to connect with them.

F is a gear wheel on the shaft e, and F, F2 are two ratchet wheels onsaid shaft, the pawls e', e2 being adapted to work in the ratchets F',F2 respectively. The ratchet F2 has a projection f on the surface whichrests in a slotf in the gear wheel F, and when said ratchet is at restis at the point f2 of said slot. The lever E has the link G connected toit at its upper end, the other end of the link Gbeing connected to thecrank disk G which is mounted upon the cam driving shaft H, which shaftis operated through the gears H2, P3, by the main driving shaft P4.

Upon the ratchet wheel F is the projection J, to which is attached arope or chain j, which passes over the pulleys lc and lo and has itsAother end connected to the weighted lever L,

which is used to put the proper tension on the warp upon the warp beamM. The gear wheel F gears into the wheel N upon the shaft ln.. Upon thesame'shaft n is the gear wheel O which works in the gear wheel P uponthe shaft p. The gear wheel P upon the shaft p works in thev gear wheelP2 upon the sand roller and during the ordinary action of the loom allthese gears are revolved continuously by the usual take-up mechanism.The spring cl2 holds the string or chain d2 so that the pawls e and e2are out of engagement with their corresponding ratchets. The string orchain is inactive in the ordinary operation of the loom, but upon thepattern chain are placed at the desired positions lugs of a greaterheight than is necessary to bring any shuttle box in use into position;and this, through the intervention of mechanism here inbefore described,causes the lifting rod a to raise an extra height. This is done at theend of the construction of a piece. This causes the chain d2 to becomeslack, and the pawls c', e2 are allowed to drop into their respectiveratehets. As the leverE is actuated by the cam shaft, as hereinbeforedescribed, the ratchet wheels revolve, which causes the string or chainj to be moved forward, lifting the weight L from the warp, and theratchet F2 revolves the gear wheel F, which, by the gearing described,causes the revolution of the sand roller to be accelerated, bringingforward the warp and enabling fringe to be formed rapidly andsatisfactorily. The cord (Z3 passes around the shaft e before it passesaround the pulley (Z7, so that the length of the said cord d3 isconstant and is not affected by the movement of the lever E. Theconnection between the gear wheel F and the ratchet F2 is made asdescribed, so that the movement of the ratchet F will lead that of thegear F and the weight will be taken off the warp before the sand rolleris operated.

A spring Sis at one end attached to the ratchet F', and the other end isattached to the floor or other fixed place, so that if sufficient fringebe not made in one motion of the lever E, and the pawls are moved backon the ratchet, the tension produced on the spring by the forwardmovement of ratchet F' will pull the said ratchet back the distance itmoved forward.

The ratchet F2 is provided with a hub having a friction face which iskept in contact with the ratchet F so that when the ratchet F is pulledback by the spring S the ratchet F2 will also be moved back a distanceequal to the length of the slot F' in the gear F, so that the ratchet F2will move that distance before it operates the gear wheel F, thusenabling the weighted lever L to be released from acting on the warpbeam before the gear wheel F is operated, so that the tension on thewarp is released before the sand roller is operated.

Instead of operating the lever E from the cam driving shaft, I canoperate it from the main driving shaft directly.

Then the machine is operating to weave the fabric, the ordinary meansare used for operating the sand roller so as to take up the wovenfabric.

Having now fully described my invention, what I claim, and desire toprotect by Letters Patent, is-
